What three things are needed to hear a sound?
In order to hear a sound, three things are needed: a source of sound producing vibrations, a medium such as air or water for the vibrations to travel through, and the ear to receive and interpret the vibrations as sound.
What three things can light rays travel thorough?
Light rays can travel through air, vacuum, and transparent materials such as glass or water. These materials allow the propagation of light by allowing the rays to pass through with little to no absorption or reflection.
What are 3 things are needed to make sound?
To make sound, three things are needed: a source of vibration, a medium through which the sound waves can travel, and a receiver to detect and interpret the sound waves.
What are the three different mediums through which waves can travel?
The three different mediums through which waves can travel are solids (such as metal rods), liquids (such as water waves), and gases (such as sound waves in air). Waves can also travel through other mediums such as plasma and vacuum.
What are three things that transfer energy through electricity?

How many regions is the pharynx divided into?
It is divided into three anatomical regions
What is a pharynx and what is its function?
Pharynx is the part of the throat that is common to both digestive system andrespiratory system. It starts behind the nose and ends in the beginning of the voice box (larynx) and the oesophagus. It is a muscular tube lined by mucous membranes that connects the nose with the wind-pipe (trachea) and the mouth with the food-pipe (esophagus) and thus acts as a common passage for both food and air. Structure of Pharynx: Pharynx is a soft collapsible tube. It is about 13 cm long in humans and lies in the front of the spinal column. The pharynx contains tonsils and adenoids (in children). Pharynx is divided into three parts namely the oropharynx, nasopharynx and laryngopharynx. Functions of Pharynx: The main function of pharynx is to act as a common passage for both food and air. Thus the pharynx should channel food without choking. Pharynx plays a major role in the first phase of swallowing. As the food bolus is pushed by the tongue into the pharynx, it pushes the food down by muscular contraction down the esophagus. The other important function of Pharynx is to equalize pressure that gets built near the ear drums. This is made possible by the two eustachian tubes (one from each ear) that connect the middle ear with pharynx. Pharynx is very soft and can be easily collapsed. Thus any physical structure can cause an obstruction in the pharynx. Pharynx is easily susceptible to infections. The inflammation or infection of pharynx is known as pharyngitis which is caused by micro organisms that enter through nose or mouth. The pharynx might collapse during sleep and the resulting condition is known as Obstructive Sleep Apnea (OSA). Any failure in the normal functioning of pharynx can cause breathing, swallowing or voice problems.

Is the oropharynx and pharynx the same thing?

How many cavities in the pharynx?
There are three cavities in the pharynx: the nasopharynx, oropharynx, and laryngopharynx. Each cavity serves a specific function in the passage of air and food.
